Function

HIN_SALTY A DNA fragment of approximately 900 base pairs, adjacent to the fljB (H2) gene, which specifies the synthesis of phase-2 flagellin, can exist in either orientation with respect to fljB. The orientation of the inversion region controls expression of fljB. The hin gene occupies about two-thirds of the inversion region; it is required for the inversion of the fljB controlling region.

Publication Abstract from PubMed

The Hin recombinase specifically recognizes its DNA-binding site by means of both major and minor groove interactions. A previous X-ray structure, together with new structures of the Hin DNA-binding domain bound to a recombination half-site that were solved as part of the present study, have revealed that two ordered water molecules are present within the major groove interface. In this report, we test the importance of these waters directly by X-ray crystal structure analysis of complexes with four mutant DNA sequences. These structures, combined with their Hin-binding properties, provide strong support for the critical importance of one of the intermediate waters. A lesser but demonstrable role is ascribed to the second water molecule. The mutant structures also illustrate the prominent roles of thymine methyls both in stabilizing intermediate waters and in interfering with water or amino acid side chain interactions with DNA.
